TYPE WRI TING MACHINE.

SPECIFICATION forming part of Letters Patent No. 705,423, dated July 22, 1902. Application filed December 17, 19CO. Serial N0. 40,099. (No model.)

out of action when the end of a short or long,

line is reached, and in order to write one or more letters or characters it has been customary to release the lockin g mechanism by hand, thus causing considerable annoyance and delay.

The object of my present invention is to 7 provide mechanism with the aid of which the difficulties heretofore encountered are overcome and various characterssuch, for instance, as a hyphen, comma, period, dash, colon,semicolon,&c.- may be imprinted upon the paper after type-bars carrying the other characters are locked out of action.

To these ends my invention consists in the novel arrangement and combination of parts to be hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a vertical sectional view from front to rear of suflicient number of parts of one form of type-writing machine to illustrate my invention. Fig. 2 is an enlarged detail fragmen tary view of a portion of the same. Fig. 3 is a detailfragmenta ry side view of a portion of the structure.

Reference being had to Fig 1 of the draW-' 'from which extend arms Z.

in a segment I and oscillate upon a pivotf,

carried by said segment. The key-levers b, that are connected to the type bars or carriers which are intended to write letters or numerals or to be locked out of operation when the end of a line is reached, are each provided with an engaging abutment or hook g. On the other hand, those key-levers b which are intended to operate the type bars or carriers that are provided with characters that it is desirable should be written after the end of the line is reachedsuch, for instance, as

the period,comma,colon, hyphen, dash, &c."

are devoid of such abutments or' hooks g, so that these keys are at all times free to be opera-ted, as will hereinafter more clearly appear.

Preferably at the front of the machine is located a rock-shaft or rod J. This rod J has rigidly connected therewith a depending arm it, that is provided with a pin 11 near its lower end. This pin i is adapted to project into a bifurcation or openingj in an arm K. This armK is rigidly connected to a rock-shaft 70, (See Fig. 3.) The upper ends of these arms Z are provided with studs'Z, which are adapted to bear'against and move a rod L, that extends from end to end of the machine, and when the rod is in the position indicated in Fig. l of the drawings it is beneath the abutments or hook-like projections g on the key-levers b, and thus prevents a depression of the key-levers, and

consequently locks the type carriers or bars out of. action. The key-levers I), being deposition. A spring Z (see Fig. 3) tends to maintain the locking-bar L in a position where the locking-abutments or hook-like projections g cannot'engage the same. When,

however, the depending arm h is oscillated, the pin 11 thereon will contact with the forward abutmentj' on the arm K and will cause the rock-shaft k to be oscillated or rocked to bring about a movement of the arms Z in the direction of the arrow in Fig. 3, and thus permit the locking-bar L to be moved to the position represented in Fig. 1 of the drawings, where it is effective to lock the lockable keylevers out of operation. The locking-bar L is rigidly connected to arms Z which are loosely mounted upon the rock-shaft 7c and which are provided with separate springs l and which teud'to move the arms Z and the locking-bar L toward the front of the machine or into the locking position, as indicated in Fig. 1. The locking-bar L is likewise connected to a button 0, as indicated in Fig. 3 of the drawings. This button projects from the front of the machine and may be moved by hand against the tension of the spring 1*, thus conveying the locking-bar out of the locking position, the slotted portion of the arm Z be tween the lugs Z allowing of this movement. The depending arm his moved to bring about the automatic movement described by the following means: A rack m is rigidly connected to and moves with the rocking bar J, and a line-stop M is adapted to move along the rocking rod or bar J and to be secured in the adjusted position by the toothed member which engages the rack m. This toothed member is carried upon a piece m, which is pivoted to the stop, as indicated at m in Fig. 1. This piece m is likewise provided with a handle or finger-piece m by which the piece may be moved around its pivot m to disengage the teeth thereof from the rack 191, when the stop M is free to be moved along the rod J. The stop M is likewise provided with an abutment m", that cooperates with a stop or abutment 72 upon the carriage. The stop M is provided with a cam m that is located to the right of the stop m. This cam m is so situated that the stop at on the carriage will first contact with it in the movement of the stop n, with the carriage toward the stop or abutment m. This contact of the stop H with the cam at will cause the inner portion of the stop M to be depressed, thereby rocking the rod J and moving the lower end of the depending arm h forward to accomplish a locking of the lockable key-levers, as heretofore described. It will be understood that the connection of the rack m with the rod J causes it to partake of the rocking movement of said rod and of the linestop, so that it at all times maintains the same relative position to the line-stop M. The line-stop M is likewise provided with a pointer m, which cooperates with a scale N, secured to the front of the machine. The carriage B is provided with a pointer n, which likewise cooperates with the scale Nto determine the position of the printing-point. It will be observed by this construction that the line-stop is so positioned at the front of the machine that it may be readily adjusted by the operator and that the locking mechanism will be automatically operated in accordance with the setting of the line-stop. Thus whether the line be long or short, as determined by the positioning of the line-stop, the locking mechanism will be automatically operated when the stop on the carriage reaches the line-stop and will prevent the lockable keylevers from being depressed, whereas any of the key-levers which are incapable of being locked may be depressed to write the hyphen, period, or such other characters as the unlockable type-carriers may be provided with. In order to release the locking mechanism by hand after it has been automatically moved to the locking position, it is merely necessary to push forward the button 0 in the manner hereinbefore described, when the lockingbar L will be moved by hand to a position where it is incapable of preventing a depression of the lockable keys.

From what has been said it will be understood that the stop M acts in a twofold capacity. It acts as an adjustable line-stop to limit the movement of the carriage at any desired point and at the same time acts as a trip for transmitting motion to the locking mechanism to automatically lock and unlock the same whether the line be long or short, as determined by the positioning of the stop. It will be further appreciated that an adjustment of a single part (the line-stop) determines the length of the line or the point where the carriage will be stopped and at the same time determines when the locking and unlocking of the type-carrier shall take place, in accordance with the length of lines to be written.

WVhile I have illustrated my invention in connection with an Underwood type-writing machinesuch as illustrated in the patent to H. L. and F. X. Wagner, No. 633,672, dated September 26, 1899-it should be understood that the invention may be applied to any type-writing machine wherein it may be found available and that various changess in construction may be made to adapt the invention to different types of type-Writing machines. It should likewise be understood that while I have described with considerable detail the construction and operation of the type bars or carriers and the key-levers and the cooperation thereof with the locking mechanism various changes may be made in the construction without departing from the spirit of my invention, which consists, broadly, in providing mechanism for locking certain of the type-carriers out of operation at the end of a line, as determined by the positioning of an adjustable line-stop, and for maintaining certain of the type-carriers free to be operated after the carriage has reached the end of the line.

Having described my invention, what I claim, and desire to secure by Letters Patent, 1s-
